China Quadrangular Tube Manufacturer, Supplier, Factory

The Qingdao Golden Land Bay project's connecting corridor features 800*300 large rectangular tubes from Spare. Pultruded and formed, each profile weighs 33 kg per meter and requires over 1,700 yarns for production. Despite its size, the corridor is 80% lighter than a steel structure of the same size, facilitating easy installation and construction. The technically challenging production process required Spare to create a specialized mold for pultrusion molding. Effortlessly lifted into place with just a wheel and axle, it saves time and effort on-site.

Explore the latest advancements and applications of Fiber-Reinforced Polymer (FRP) that are driving innovation and sustainability in various industries.

The FRP cooling tower at the Shanghai Laogang Renewable Energy Utilization Center Phase II Project, designed by SPX Company, incorporates SPARE company's FRP materials for enhanced performance. With a mechanical ventilation mist elimination design, it efficiently handles 4000m3/h of cooling water per tower, totaling 40000m3/h. The tower group, arranged in a single line on the southwest side, consists of two sets of five towers each, with a shared circulating water pump room nearby. Each tower, utilizing SPARE's pultruded FRP frame structure, stands at 21.2 meters tall and 21.1 meters wide, offering both strength and lightweight characteristics, with over 400 tons of FRP pultruded profiles used in total.

FRP rectangle tubes are made from materials such as epoxy resin and high molecular weight unsaturated polyester resin, which effectively resist acid and alkali corrosion in practical applications. They are also suitable for transporting some corrosive chemical reagents and liquids.

SPARE Composite, a global leader in FRP (Fiber Reinforced Polymer) products, is announcing the upcoming release of its innovative FRP pallets. These pallets are designed as a superior alternative to traditional wooden pallets, offering unmatched durability, environmental benefits, and cost efficiency.

Fiber Reinforced Plastic (FRP) plays a pivotal role in revolutionizing the automotive industry, offering a myriad of applications owing to its lightweight, high strength, and exceptional corrosion resistance properties.
